Thanks for your answers.

Try to make things clearer:

"Professional" to me is when they want to make money with programming (as I do, in a very different field). And I expect from a professional that he/she is able to make a program work out of the box, not that I have to contact the support even to install the software. I do not mean professional features, I mean handling the very basics (like paths, access rights etc., to know what a home directory is).

I can forgive a lot if I try a free program. See Blender. It has highly professional features but the user interface is terrible. It's free - and it's ok. Vue on the other side seems to be designed as a money mashine. Should I really hope the "Pro" version will handle paths the right way? That hope may come expensive...
